We Cracked It
PETD technology breaks the ice bond almost instantaneously, inexpensively and with dramatically less energy than current technology.
Where can we break ice? ● ● ● ● ● ●
Ice makers Power lines Windshields Wings and wind blades Bridges, buildings and ships Refrigerators and air-conditioning ...and more
Premise Ice Making
PETD Ice Makers use 40% less energy
Energy consumption
It takes almost as much energy to release ice from the tray as it does to freeze it
Premise Auto PETD equipped windshield clears ice in seconds

Premise Wind blades
PETD wind blades eliminate wind turbine down-time due to icing See video SPECIAL NOTE: On November 16, 2010 PETD was named one of five innovation award winners of the ‘GE ecomagination Challenge: Powering the Grid.’
World wide, lost power production due to wind blade icing averages 10% in cold climates.
Premise Power Grid
VRC technology melts ice from power transmission lines without service interruption. There is no other known solution.
Today, the US power grid is over-capacity causing massive loss of heat energy. VRC means higher capacity lines can be employed improving transmission efficiency by up to 25% for over 50% of the grid worldwide.

PETD-I
Pulse Electro-Thermal Deicing (PETD) (technical paper) PETD concentrates a “smart,” precise, high power pulse to the ice/substrate interface for between .01 - 4 seconds to heat a minimal layer of interfacial ice to just above the melting point causing the ice to slide off a resulting thin water film.
SPECIAL NOTE: On Nov 16, 2010 PETD technology was named one of five innovation award winners of the ‘GE ecomagination Challenge: Powering the Grid’ For wind turbine blade deicing.
"An ice surface has a high electric charge. Ice doesn't simply cake onto surfaces, it bonds in three ways: via the hydrogen atoms themselves, via an electrostatic bond caused by the current and via comparatively weak van der Waals forces. There is no surface coating which can suspend those three forces. That is why the search for ice-phobic coatings has failed. PETD melts just a few microns of the ice interface and gravity does the rest." - Dr. Victor Petrenko
State of Technology
Plane Deicing
PETD will replace chemical deicing “The chemicals normally used to deice aircraft - ethylene glycol and propylene glycol are both deadly substances even in small quantities. Ethylene glycol causes central nervous depression and kidney and liver damage and propylene glycol is just as toxic. While no studies have been done on its effects on humans, each winter large amounts of fish and wildlife are poisoned to death by aircraft deicing chemicals. Additional pollutants, including fuels and other toxic substances, are also washed off the planes during deicing procedures. Compared to the rest of components of aircraft pollution, this is a minor one, though it could have harmful effects on those few who perform this activity, and on some unfortunate fish and fowl. This aspect of aircraft pollution has not received much attention so far.“- Source

:Uddevalla Bridge: Current Projects
Uddevalla Bridge, Sweden
PETD technology was tested in Sweden in 2006 where a 1712meter-long "cable stayed" bridge has major problems with icing and must be closed down for significant periods of time during the winter months due to dangerous chunks of ice falling at random off the towers and cables from heights of up to 140 meters.
Each steel cable is covered by a thin polymer tube (wrapped in stainless steel foil) to prevent rusting. "We apply [an] electric pulse to either end of the cable for about one second," Petrenko says, "and all ice attached to it falls down." - Scientific American article
The first tests of PETD demonstrated instant deicing action with minimal energy investment.
